Produal RTX | HVAC Room Transmitter
- Manufacturer: Produal
- Category: SENSORS, Gas Sensors, Humidity Sensors, Temperature sensors
Accurate monitoring of temperature, humidity, CO₂, and indoor air quality is essential in smart buildings, offices, hospitals, hotels, educational centers, and modern HVAC systems. Produal RTX ambient transmitter It is designed to centralize these measurements in a single device, facilitating the monitoring and control of HVAC/R, BMS and building automation systems.
Depending on the version selected, the device can measure temperature, relative humidity, CO₂ concentration, volatile organic compounds (VOCs), and presence using a PIR sensor. Thanks to its accuracy of up to ±0.3 ºC In terms of temperature, it allows for improved thermal regulation, optimization of indoor comfort, and provides reliable data for the building's energy management.
The RTX is not limited to measuring environmental variables. It incorporates a integrated P/PI controller Capable of controlling heating, cooling, ventilation, humidification, and dehumidification. The control output can operate based on a single variable or by maximum selection, automatically prioritizing the environmental variable that generates the greatest control demand, whether it be temperature, humidity, CO₂, or VOC.
To facilitate integration into new or existing installations, it features a multifunction input compatible with PT1000, NTC10 sensors, digital, resistive and 0-10 V signals, plus up to four configurable outputs of 0-10 V, versions with relay output and communication Modbus RTU either BACnet MS/TP via RS-485. This allows it to be connected directly to PLCs, HVAC controllers, VAV units, and centralized technical management systems.
Models with relative humidity also incorporate advanced functions such as dew point calculation and condensation alarm, especially useful in air conditioning installations, air ducts, cold water pipes and surfaces where condensation formation must be avoided.
The configuration is done through the application. MyProdual and the adapter MyTool Connect, reducing start-up times and facilitating the adjustment of measurements, outputs, alarms, communication and control functions.
RTX Ambient Transmitter Applications
The Produal RTX is commonly used in HVAC/R systems, smart buildings, offices, hospitals, hotels, educational centers, laboratories, VAV units, technical rooms and BMS systems where continuous monitoring of temperature, relative humidity, CO₂, volatile organic compounds (VOCs) and occupant presence is required.
